Problems solved by technology

Field application and practice have proved that the conventional oil-water well producing status analysis method has high credibility and applicability for sandstone reservoirs with small production intervals, few perforated layers, and weak reservoir heterogeneity. Strong; but for complex fault-block fluvial reservoirs with strong reservoir heterogeneity, long

Embodiment Construction

[0033] The core of the production splitting part of the software consists of KH value splitting device, oil well water absorption pretreatment device, water absorption profile splitting device, dynamic personnel subjective analysis splitting device, small layer weighted splitting result device, and single sand body splitting result summary device composition.

[0034] After the user prepares all the data required by the system through the input interface and importing external data, the data check is performed first to ensure the correctness of the data. If there is an error, the user is prompted to modify it. Then perform data preprocessing, establish temporary data tables, connect and process related data tables, and insert preprocessed data into corresponding temporary data tables.

[0035] The data in the pre-processed temporary data table is sent to the following devices for single-factor yield splitting: 1. KH value splitting device; 2. Oil well water absorption pretreat...

Abstract

It relates to the after potential exploration of an oil filed, with the ability of analyzing the oil distribution, left resource quantity, and so on. It comprises the data inspection device, data preprocessing device, KH value separation device, oil well water absorption preprocessing device, water absorption section separation device, dynamic personnel analysis separation device, small layer weighting separation device, single sand separation result accumulation device, data base, water filling effect, strata HK, and weighting of the oil reserve weighting by the dynamic personnel, determining the strata output through the water absorption section, water content of the strata through well fluid section, with the whole process being computerized and accurate.

Description

technical field [0001] The invention relates to a method for tapping the potential in the late stage of an oil field, analyzing the remaining oil distribution of each oil sand body, quantifying the remaining resource amount of each oil sand body, and proposing the production status of oil-water wells in complex fault block fluvial facies reservoirs in the direction of potential tapping. analysis system. Background technique [0002] my country's oilfields are mostly onshore oilfields with developed fluvial reservoirs. There are many faults and complex structures. The distribution of oil layers is controlled by both structure and lithology, and the continuity is poor. There are many relatively independent oil sand bodies scattered in the oil reservoirs. Due to the complexity of reservoirs, the diversity of mining methods, and the constant adjustment and potential excavation work, the distribution of remaining oil becomes highly dispersed and extremely complicated both horizon...
